  Next, with reference to FIG. 3 and FIG. 4, a substantial configuration of each element of the upper imaging / illumination unit 22 and the lower illumination unit 23 will be outlined.

  The upper imaging / illuminating unit 22 includes a box-shaped upper casing 51, and the above-described elements are mounted on each part of the upper casing 51.

  In FIG. 3, the power supply unit 25, the data processing unit 34, the image sensor 33, and the lens 32 </ b> A constituting the optical system 32 facing the lower illumination unit 23, which are a part of the upper imaging / illumination unit 22, a plurality of components. The LED element 31 </ b> A is used to arrange an upper light emitting unit 31 facing the lower illumination unit 23, and a constant voltage circuit 44 that applies a predetermined voltage to the upper light emitting unit 31.

  The lower illumination unit 23 is configured as a transmitted light type and includes a box-shaped lower casing 62. As shown in FIG. 3, the lower casing 62 includes the upper light emitting unit 31 and the optical system 32. The lower light emitting unit 43 is disposed so as to face the lens 32A constituting the lens, and the tray 24 is placed on the lower light emitting unit 43, and the power supply unit is disposed in the lower casing 62. 36 shows a configuration in which a lower illumination unit controller 37 and an imaging illumination controller 41 are arranged.

  The lower illumination unit 23 is, for example, an illuminant that includes a backlight, an LCD, an OLED (organic EL display), or the like, and has a plurality of light emitting points that can arbitrarily control the intensity of light.

  When the lower illumination unit 23 is used, measurement with transmitted light is possible without using a perforated tray, so that it is not necessary to arrange the particles to be measured on the perforated tray, and the time required for measurement preparation is reduced. There are advantages to being.

  FIG. 8 shows an example of a torn grain image captured by the image sensor 33 using the lower illumination unit 23.

  Here, a supplementary explanation will be given regarding the presence / absence of the body split of the grain and the shade of the image.

  When light is applied to a part of the sample to be measured, the portion that is exposed to the light becomes brightest, and as it gets farther from the light source, it scatters and reaches the inside of the sample and becomes darker.

  When the measurement target is a grain, the change in the brightness of the grain image looks smooth as shown in FIG.

  On the other hand, in the case of a grain having a crack due to a torso, light is strongly scattered at the crack portion, so that a drastic change in brightness is observed before and after the crack as shown in FIG.

  In the present embodiment, it is clear from FIG. 8 that the image of the lower illumination unit 23 is bright and dark due to the center split of the split grain on the light emitting point on the LCD having the backlight, for example. did.

  On the other hand, in the case of the lower illumination unit used in the conventional grain discriminator, since the emission point of the transmitted light is determined, the illumination direction is constant with respect to the axis of the grain to be inspected, for example, when discriminating torn grains Had to keep on.

  In addition, in the conventional transport disk type grain discriminator, since the measurement is performed for each grain, the time for physical movement of the grain is limited in addition to the image processing time. There is an inconvenience that a plurality of measurement systems are necessary, for example, it is necessary to distinguish between split grains and heart white grains using different light sources.

  Furthermore, in the case of a grain discriminator using an image scanner, there is an inconvenience that it is indispensable to place it on a tray with a grain hole.

  FIG. 4 shows a schematic cross section of the upper imaging / illumination unit 22. A main board 52 is horizontally arranged in the upper housing 51, and the image sensor 33 is placed by the image sensor board 53 at the center of the main board 52. Further, the lens 32A is supported by a lens barrel 54 attached to the lower portion thereof, and a polarizing plate 55 is attached to a lower end portion of the lens barrel 54.

  Next, the grain discrimination process by the grain discrimination system 61 combining the imaging device 21 and the operation panel type information terminal 1 according to the embodiment of the present invention will be described.

Further, detection other than torso cracking is performed by image processing in the operation panel type information terminal 1.

(B) After the lower light emitting unit 43 is turned on, an image of a grain is captured by the image sensor 33 with transmitted light to obtain image data. Then, crack detection is performed by image processing in the operation panel type information terminal 1.

(C) Depending on the result of the above processing, as shown in FIG. 11, the lower light emitting unit 43 is turned on with a different pattern to detect white immature grains, and the second imaging with transmitted light is performed. That is, as shown in FIG. 11, in addition to imaging of white particles using reflected light, imaging of white particles using transmitted light (entire light emission from the entire surface: light emission points), transmitted light (spot: light emission from some light emission points). ).

(D) Depending on the measurement item, the lower light emitting unit 43 is turned on in a different pattern to detect colored particles or the like on a surface far from the image sensor 33, and imaging is performed three or more times with transmitted light. That is, as shown in FIG. 12, in addition to imaging of colored particles (front) by reflected light and imaging of colored particles (back), imaging of colored particles (back) by transmitted light (entire emission of all emission points). The colored particles are imaged (back) by transmitted light (spot: light emitted from some light emitting points).

(E) With the illumination method as described above, it is possible to measure the state of the inside / back side of the sample that cannot be seen from the image sensor 33 in the conventional reflected light image, and the image sensor 33 is not disposed above and below the sample. There is an advantage that it may be.
